Natural and human-induced impacts on coastal groundwater

Groundwater
is the main source of potable water in most areas of Mazandaran province, like
Sari and Babol city. Thus the safety of groundwater supplies is very important
in these regions.3 are
within WHO standard limits, but Pb, Se and Cd concentrations are often
exceeding the WHO maximum permissible standard values. Results show that the
current quality of groundwater in Mazandaran province does not present
immediate health related concerns. However, the quality of water wells in
Mazandaran province is not reliable because of relatively high rate of various
pollutants discharges into groundwater resources. Consequently, establishment
of both monitoring programs and appropriate regulations to minimize
uncontrolled discharges into groundwater resources is necessary for conservation
of this valuable source of water supply in Mazandaran province.

Poor sanitation can contaminate drinking water, especially in rural areas. Unless properly dealt with, faeces and other human waste can pollute the soil and eventually wells, causing diseases such as diarrhoea.
The EcoSanitation method provides a safe way to dispose of human waste. Today, a research project in Tanzania examines the potential of combining this system with a composting technique called Terra Preta.

Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly include land filling, separating waste and composting, biomethanation, incineration, and conversion to refuse derived...

The social, economic and technological growth of a developing society has resulted in rapid product obsolescence which in turn has become a new environmental challenge – i.e., ‘electronics waste’ (e-waste). Electronic waste has not been a problem as long as there were a few computers or other electronic devices on earth. With the increasing use of computers/electronic devices, our planet has become a dump house for electronic wastes. Electronic products often contain hazardous materials that lead to environmental...

Every day a huge amount of excreta is being produced by human society and it is also considered one of the most unwanted waste/refuse of the society because of its nuisance and diseases causing characteristics. However, it is also utilised as a fertiliser and soil conditioner in several countries such as India and China. Presently most common sanitation concept is centralised treatment of human excreta containing wastewater, in which a small volume of excreta is being mixed with large volume of water, and transport...
